'Appl'iatio fed April' Tl', 1922. ferial No. 552.714.

T o @ZZ whom i may o0/noem Be it known that I. Banen l. YOUNG, a citizen of the United States, residing at Odel, in the county of Gage vand'State pf Nebraska` have invented new and useful iniprovements in Lubricating Devices, of which the following is a specificati-on.

This invention relates to lubricating: devices, and an ohect of the invention is to provide a lubricatingV device comprising@r an oil cup and means for dispensing lubricating oil therefrom, the said means providing a positive uniform feed of lubricant which embodies a minimum amount bf vaiiation due to thick or thin oil or variation in temperature1 and a mechanism which is designed to properly feed the lubricant indepcndenthv of the temperature thereof, eliminating! need of adiueting the mechanism when the oil becomes Warm or heated, and it also eliminates the Vdanger of burned bearings or scored cylinders due to irnproper lubrication caused b v the emptying of the oiler 'when the oil becomes heated such as is the case in approved types of drip cup oilers.

Another object of this invention is to provide a. lubricating,y device inwhich the quantity of lubricating oil fe'd to the working parts is in direct proportion to increase in speed ofthe rotatable or movable meinber to be lubricated, and further to provide a device which eliminates uncertainty in the lubricating action of working parts and also eliminates the necessity of frequent attention thereto, the said attention only being necessary for refilling purposes.

Other objects' of the invention will appear in the following detailed description taken in connection with the accompanying drawings wherein: i y

Fig. 2 is a vertical section through the luh-ricator. Y

Fig'. 6 is a horizontal section through the lubricatorf.

Fig. 7 isA a fragmentary vertical section on the line 7&7 of Fig. 6.

Fig. 8 is a fragmentary verticai section taken on the line 8-8 of Fig. 6.

Fig. 9 is a detail vertical section taken on the line 9-9 bf Fig. 6.

Referring more particularly to the drawings.y the improved lubricating device comprises a supporting base 1 having a threaded stein 2 therein which is adapted for thread ing into the bearing of a suitable rotatable or movable member to permit lubricant pass-- ing through the passageway 3 to lubricute the working surface. The supporting base 1 is provided with a flat supporting disc 4 on its upper end against which a worm gear 5 rests, the said worin gear being` forced into tight engagement with the upper surface of the disc by means of the pressure disc 6 and spring 7 which act thereon. The Springr 7 is coiled about the Vconnecting; bolt 8 which is threaded inl o the body 1 and projects axially through the cylindrical cup 9. extending through the apex of a conical top 10. A nut l1 is adjustably mounted upon the upper end of the bolt S for clamping the cylindrical cup 9 against the gasket 11 which rests upon an annular shoulder 13 and also claihps the conical top l0 against the gasket 14 which rests against the top edge of the cup 9 se curelv connectingr the cup, top and base. The annular shoulder 1B is in turn formed upn the annular flange l5 formed about the perimeter of the disc 1;

The bolt 8 acts as an axis for the Worm geur 5 which gear is rotated from a shaft 16 by means of the worin 17 for bringing one of the openings 18 therein in registration with the openings 19 in the disc 6 to permit a quantity of lubricant io pass through the openings 19 into the opening 18. and as the gear continues to rotate'. the respective opening 18 is brought into registration with an openingr Q0 in the base 4 at which time the lubricant is `forced but of the openinjiV 18 through the opening 2U into the inclined pasagreway Q1 by means of aspring actuated pawl 22. The pawl 22 is slidably supported Within a suitable guiding; housing QB and is urged outwardly by means of a spring 24 into the position as indicated in Fig; 7 of the drawings Whi h will force alll of the lubricant out of the openings in the gear 5, through the opening 2O and into the passageway Q1. The edges 95A of the openings 18 are beveled as clearly Shown ,in Fig, 7 of the drawings, to force the paWl upwardly. to permit` unimpcded rotation of the gear 5 and permit the pawl to act on the lubricant carried by one of the other openings in the gear. as the opening is moved into alignment with the paivl. The lubricant passes through the passageway 2l into the pocket 26V from where it passes into and through the passageway Il to thc surface to be lubricated. The pressure disc G is held against rotation by a lug 2T formed on the flange t4 and enpaging in a suitable recess Q8 formed in the perimeter of the disc.

The shaft i6 may be connected to any suitable driving shaft or mechanism for rotating the worm li' which will in turn rotate the Worm gear 5 moving it about so that the openino's 1S will successively register' with the openings 'i9 and receive quantities of lubricant therein. Which lubricant will be forced out of the openings in the gear and into the passageway 21 by the pawl when the respective opening i8 is moved into registration with the paivl.

From the foregoing description taken in connection with the accompanying drawings it will be apparent that the improved lubricating device will feed a pre-determined quantity of lubricant. uniformly. to the surface to be lubricated. irrespective of the density of the lubricant and also irrespective oi the tel'nperature of the lubricant or the bearings.

It is. of course. to be understood that the invention may be constructed in other man4 ners and the parts associ ated in different relations and. therefore. I do not desire to be limited in any manner except as set forth in the claims hereunto appended.

Having thus described my invention what I claim is:

l. In a lubricating dispensing device. a lubricantcontainer. a carryingr body theretor provided with an outlet passageway. a Worm gear rotatable within said body and provided with a plurality of lubricant receiving openings. means for rotating said Worm gear. and a spring pressed pavvl operating as a plunger for forcing lubricant from said openings upon movement of the openings into registration with said passage- Ways.

2. In a lubricating dispensing device. a carrying body provided with an outlet passageway. a lubricant container carried by 'said body. a horizontally rotatable Worm gear Within said body and provided with a plurality of lubricant receiving openings, means for rotating said ivo-rm gear. a disc Within said bodyv between the Worm gear and lubricant. said disc provided with a plurality of openings to permit, deposit of lubricant in the openings of said worm gear. said Worm gear openings adapted to discharge their lubricant upon their registration with said outlet passageway, and a spring pressed paivl operating as a plunger carried by said disc for projection through the lubricant carrying openings in said ivorni gear to force Vlubricant therefrom.

In a lubricating dispensing device7 a carrying body provided with an outlet passageway, a lubricant container carried by said body. a horizontally rotatable worm geur within said body and provided with a plurality of lubricant receiving openings. means for rotating said Worm gear. a disc Within said body between the Worm gear and lubricant, Said disc provided with a plurality of openings to permit deposit of lubricant in the openings of said worm gear. said worm gear openings adapted to discharge their lubricant upon their registration With said outlet passageway, a spring pressed pawl operating as a plunger carried by said disc for projection through the lubricant carrying openings in said worm gear to vforce lubricant therefrom, means for preventing rotation of said disc. and a pressure spring engaging said disc and forcing it into engagement with said Worm gear.

4. In a lubricating device, a'lubricant container. a rotary member provided with lubricant receiving openings, an outlet passageway, and a spring pressed pawl operating as a plunger for forcing lubricant from said openings upon movement of the openings into registration With said passageway.
